Sept 8,. 1942 A. w. KANDETZKI VACUUM CLEANER Filed Oct. 6, 1959 INVENTOR.

Pat ent ed Sept. 8, 1942 VACUUM CLEANER AlbertWilliam Kandetzkl, Stamford, Conn, as-

signor to Electrolux Corporation, New York, N. Y., a corporation of Delaware Application October 6, 1939, Serial No. 298,211 4 Claims. (Cl. 280-12) My invention relates to vacuum cleaners vnd more particularly to a support therefor.

Vacuum cleaners of the, so-called, inside-bag type have a casing in which the operativemechanism is mounted and in which the dust collecting bag is located. It has been found convenient to provide sleighs for supporting this unit on a flat surface. Usually two sleighs are provided and attached to opposite sides of a casing and extend substantially the length of the casing. The operative mechanism mounted in the casing produces vibrations due to the operation of the motor and to vibrations in the air flowing through the unit. If the casing is supported on a hard surface, such as a bare floor or linoleum covered floor, these vibrations may be transmitted through the sleighs to the supporting surface' thereby creating undesirable noise.

In accordance with my invention, sleighs are provided for supporting a vacuum cleaner casing with resilient means for preventing the transmission of vibrations to the sleighs eliminating any noise which may be generated thereby. Also, the resilient means reduces the transmission of shocks from the sleighs to the casing.

What I consider to be novel and my invention may be better understood by reference to the following specification and appended claims when considered in connection with the accompanying drawing, in which i Fig. 1 is a side view of a vacuum cleaner with my improved supporting means;

Fig. 2 is a front view of the vacuum cleaner with the cover removed;

Fig. 3 is a side detail view of the supporting Fig. 4 is a sectional view taken along the line 4 4 of Fig. 3; and

Fig. 5 is a detail view of the resilient bushing. The numeral l0 designates a vacuum cleaner casing in which a dust separating bag II is 10- I cated together with a motor-fan unit l2 for producing a flow of air through the casing. Casing I0 is provided with a handle I3 which may be utilized for moving thecasing Ill from one place to another. At the front end of casing [0, a cover [4 is provided, shown at the left in Fig. 1, which is detachably secured by means of spring clips [5 to the casing 10. Cover 14 is provided with an inlet opening in which a flexible hose I6 is connected for communicating the suction to a cleaning tool [1 which may be connected directly to the flexible hose [6 or through the intermediary of a rigid handle member [8.

At each end of the casing l0, reinforcing rings 55 25 in the bracket 2 l. The end flanges 23 and side projection 24 prevent longitudinal and radial movement of the bushing 22 within the bracket 2 I.

The bushings 22 may be secured directly to the ends of sleighs 20 as by means of molding thereon. However, my invention is not limited to themolding of the bushings 22 on the ends of the sleighs 20, as they may be positioned loosely and secured by the friction therebetween. The internal opening of the bushing 22 may be made somewhat smaller than the exterior dimension of the sleigh 20 so that the bushing 22, when once forced on the ends of the sleigh 20, will have no tendency to move with respect to the sleigh 20. The brackets 2! are secured to the rings 19 by means of screws 26, or the like. The brackets 2| are formed from a single strip of metal bent back on itself with a substantially cylindrical portion 21 for receiving the bushing 22.

In the operation of the vacuum cleaner, the casing I0 is located on a supporting surface in the vicinity of the area to be cleaned. The cleaning tool I! is reciprocated back and forth over the surface being cleaned within a given area. As the cleaning tool I! is moved from one location to another, the casing I0 may be moved by force applied tothe flexible hose I6. If. the casing I0 is resting on the rug, or other relatively soft material, there will be no tendency for vibrations ofthe casing It to produce a noise. However, it is frequently found desirable in cleaning various surfaces to locate the casing III on a bare floor oron a. floor covered with a relatively hard material, such as linoleum. Such a surface is sufficiently hard so that any vibrations transmitted from the casing It to the surface would generate a noise.

By the provision of the supporting means, including the sleighs and the resilient bushings 22, any vibrations generated within the casing l0 are not transmitted to the sleighs 20. This prevents the vibrations within the casing l 0 from generating noise when casing 10 is supported on a relatively Sleighs 20 are connected to end.

hard surface. In moving the casing It from one room to another, or some distance, it may be convenient to carry it'by the handle it In the handling of household appliances the utmost care is not always exercised. I! the handle I; should be released before the casing II is resting on a supporting surface, a considerable shock maybe transmitted to the operating mechanism, such as the tan unit I! within the casing Ill. The serious consequences of such shocks are greatly reduced by the interposition of the resilient b I ings 22 between the sleighs 20 and the casing ll. These sleighs and the resilient bushings 22 absorb much or the shock, and so do not transmit it to the casing II and the motor-Ian unit l2.

Thus, by this arrangement the danger or vibration or undesirable noise is eliminated and the possibility of damage to the vacuum cleaner is greatly reduced.

It is to be understood that while my invention has been illustrated by a speciflc embodiment for the purpose of the description, it is not limited thereto but modifications may be made within the scope of the appended claims.

What I claim is:

1. In a vacuum cleaner including an elongated casing, the combination with said casing, of means for supporting said casing on a flat surface including sleighs, brackets secured to said casing having openings in the sides, and cylindrical members or flexible material located between the ends of said-sleighs and said brackets and having projections entering the openings in said brackets.

2. In a vacuum cleaner including an elongated casing, the combination with said casing, of

means for supporting said casing on a flat surface including sleighs, a bushing of resilient material secured to the ends of said slelghs having end flanges and a side projection, and a bracket secured to said casing extending around said bushing between said flanges and having an opening to receive said side projection.

3. A suction cleaner of the inside bag type comprising an elongated casing for the operating mechanism, elongated supporting runners adapted to permit said casing to be readily moved about in spaced relationship to a substantially flat surface, said supporting runners being attached to said casing at'a plurality of points on said casing, resilient shock absorbing means interposed between said supporting runners and said casing at said points of attachment, said resilient shock absorbing means and said supporting runners being constructed and arrangedto reduce transmission of shock from said runners to said casing and to concurrently reduce transmission of sound and vibration or the cleaner operating mechanism from said casing through said runners to said surface, and means for holding said resilient shock absorbing means in cooperative relationship with said casing-and said runners.

4. In a vacuum cleaner, including an elongated casing, the combination with said casing of means including sleighs for supporting said casing on a flat surface, brackets secured to said casing having openings in the sides, and flexible members located between the ends of said sleighs and said brackets and having projections entering the openings in said brackets.
